KINEMATOGRAPHIC CAMERA.

Specification of Letters Patent.

Patented Feb. 2o, 190e.

Application led April 7'1905. Serial N0, 254,398-

TO ,a1/ZZ whom, it mfG/,7] concern:

Be it known that I, MAX HANSEN, a subject of the German Emperor, and aresident of Berlin, in the Kingdom of Prussia, in the German Empire,have invented new and useful Im rovements in Kinematovra hic'Cam-v eras,o f which the following is a specification.

My invention relates to an improved camera primarily intended for.so-called living or l animated photographs, and more particularlyadapted for amateurs, being of exceedingly simple construction and atthe same .time applicable for divers uses in addition to its mainpurpose.

An essential feature of the invention is that the actuating mechanismwith simple feeddrums does not require the assistance of any specialrollers or the like for winding the film with positive motion for theexposure, the exposed film-band running unconstrained into the rearchamber of the ap aratus.

The invention is illustrated 1n the accompanying drawings, in which-Figure l is a vertical section of the apparatu's, a central part beingbroken away to save space. Fig. 2 is a horizontal section of the frontportion of the same. FigyB is a vertical section, drawn toasmallerscale, ofthe apparatus' arranged as an ordinary camera, acentral portion being omitted to economize space on the drawings.

The actual operating mechanism is carried by a plate b, perforated at tto admit of exposure and having hinged to it at h the filmguiding fiapor late h, which carries the two film-pressing ro lers g.

p is a bent guide for assisting in conducting the film i in the rearchamber of ,the apparatus, where it can fold itself into any shape quiteunconstrained. This rear chamber is sufficiently large to containseveral yards of film, such as is ample for the average amateur. Iflonger lengths of film are to be accommodated and it is not desired touse special holders with Winding mechanism, the camerabody may beextended by one or more additional receptacles being joined on .behindand the wall l removed.

The film-feed Wheels 0r drums e and the instantaneous shutter f areactuated by a crank applied to the squares ofthe axesc and d. By singlerotation ictures-that is to say, serial p1ctures-will iie exposed. Eachtime the axis d is rotated, on the other hand, single pictures will beproduced. As the drawings show, the rollers g of the axisc a largenumber of I press constantly against the film i., which insures that thestuds of the feed-drums e always retain their hold on the film. Thelatter, therefore, is permanently held both during the periods ofexposure and arrest and can never fall back ofi' the drum-studs or getotherwise displaced..

The plate b is shown as fitting at c into grooves in the walls of thecamera-body c; but other suitable means may be employed to hold theplate t so long as they admit of its being (together with the mechanismmounted on it) readily inserted into or removed from the camera. Thelatter is provided with a door a', hinged at a2 c, to allow access tothe interior a. When the inner detachable part is removed and thewithdrawn, the apparatus can be employed as an ordinary camera, a darlislidel being employed, and the holes for the axes c cl closed insuitable manner.

It Will be observed that the late b constitutes a partition foreffective y closing the rear chamber with the exposed unconstrained fromcatching in any mechanism.

The apparatus may also be used for printing purposes. Furthermore, theactuating mechanism, with its plate I), if removed and placed before amagic lantern, may be used or projecting living pictures, the part 71,being replaced by. a suitable slotted member. The so-arranged'actuatingmechanism may be again introduced into the body a and the apparatusemployed for simply observing pictures without projection. The lens isin such case used as magnifyingocular and the back Zremoved to admitlight and allow the film to run, out, or a slot furnished with asuitable closure may beprovided in the base of the body a to admit ofexitof the film.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

' 1. In a kinematograrhic camera,- in combination, a camera-bo y, aperforated support'in the body of the camera, actuating mechanismpresenting feed-drums mounted parts of the actuating guiding means andfilm-pressing means c arried on the back thereof, and a film-bandlocated on the rear side of the support and fed by the said drums andconstantly forced inserted, as shown in Fig. `3, a suitable lens andclosed by a catch spindle o, which carries the filmt, likewise film-bandwhereby also the film is prevented IOO entirely on the lfront ofthesupport, filmagainst them by the said pressing means and ruiming withunconstrained motion, as dif Jferentiated Jfrom those devices providedwith positive Winding means, substantially as described. Y

2. In a kinematographic camera, in combination, a camera-body, aremovable perforated support itting into the camera-body, actuatingmechanism mounted entirely on the front side of the support,film-guiding means carried on the back thereof, and a nlm-band locatedon the rear side of the suport and fed by the said actuating mechanismand running with unconstrained motion, as differentiated from thosedevicesprovided with positive Winding means, substantially as described.

3. In a kinematographic camera, in corn bination, a camera-body, aremovable erforated support itting into the cameraody, actuatingmechanism mounted entirely on the iront side of the su port, andilm-guid ing means carried on t e back thereof, substantially asdescribed.

4. In a kmematographic camera, in combination, a camera-body, aremovable perforated su port fitting into the camera-body and dividingit into a front and a rear chamber, actuating mechanism-mounted on thefront side ofthe support, and Jfilm-guiding means carried on the backthereof, substantially as described.

5` In combination, a camera-body having a removable back, a removableperforated support in the camerabody, actuatin mechanism mounted on thefront side of t e sup' port, film-guiding means carried on the backthereof, and a film-band located on the rear side of the support and fedby the said actuating mechanism and running with unconstrained motion,as differentiated from those devices provided With positive Windingmeans, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing Witnesses.
